During endodontic treatment, clinicians may face endodontic procedural mishaps such as broken instruments, which is a complex situation especially when the file breaks beyond the apex. This condition is associated with potential risk of contamination, which compromises the healing process. Management of a broken instrument beyond the apex is difficult and time consuming and requires creativity ...

One of the most common procedures performed in orthopedics is knee arthroscopy, and a variety of complications are found with this procedure. One of the most avoidable complications is that of retained instruments. This article describes the case of a patient in the private practice orthopedic setting who returned 6 years after a knee arthroscopic procedure reporting acute onset pain. It was di...

BACKGROUND To investigate differences in the estimated minimum remaining dentin thickness (RDT) between periapical radiographs using the paralleling and parallax technique, after simulated removal of broken instrument from the mesiobuccal (MB) canal of maxillary first molar in virtual simulation model. The 3D measurement was taken as the standard for comparison. METHODS Thirty-six maxillary f...

A variety of metallic objects broken by the dentist or the patients have been discovered inside the root canals. A number of techniques are mentioned in the literature for the retrieval of these foreign objects from the root canals with minimal loss of tooth structure and to avoid surgical intervention. Most of these techniques are effective for the removal of broken files/instruments. But ther...

It gives me great pleasure to deliver the keynote address at the Asian Bond Conference organised jointly by the Thai Bond Dealing Centre (Thai BDC), Fixed Income Money Market Dealers Association of India (FIMMDA) and Primary Dealers Association of India (PDAI). It is a matter of significance that some of the major self-regulatory organisations (SROs) in the debt markets of Asia have taken this ...

INTRODUCTION The aim of this study was to compare the shaping ability of two single-file systems and conventional rotary instruments in severely curved root canals of extracted human molars. METHODS AND MATERIALS Mesiobuccal canals of 120 mandibular molars with angles of curvature ranging between 25(°) and 35(°) and radii of curvature from 5 to 9 mm, were divided into three groups (n=40). In ...

ABSTRACT Motor current signature analysis has been successfully used for fault diagnosis in induction motors. However, this method does not always achieve good results when the speed or the load torque is not constant, because this cause variation on the motor slip and fast Fourier transform problems appear due to non-stationary signal. This paper experimentally describes the effects of rotor b...
